LAND-ROLLER.

' Specification of Letters Patent. Pate ted June 18, 1918.

' Application filed-August 5, 1916. Serial No. 113,403.

To all whom it may concern Be it known thatLGEoRon WRIGHT, a citizen ofCanada, residing at Chatham, the county: of Kent and Province of-Ontario,

Canada-,- have invented new and usefulIrnprovements in Land-Rollers, ofwhich the following is a specification.

My inventionrelates to improvements in land rollers the objects thereofbeing to providea-roller'that will roll uneven ground with equalpressure whether it be a knoll or hollow.

The frame of my roller can be made lighter than ordinarily, as thedralft is directly from the rear in the middle between the two rollers;also, in my invention the rollers are l closer together endwise, andtherefore, leave a smaller ridge between the rollers.

I attain these objects in manner as illustrated in the accompanyingdrawings, in Which':-'

Figure 1 is aperspective' view of the coml Fi 3 i a crosssection'of asingle roller plete rollers; g

Fig. 2 is a front'view, the dotted lines showing how each section actson uneven ground through 1-2 of- Fig. '1 i t Fig. 4' is an endview; ofroller'with'part cut away showing the connection of the draw rodfromtongue to rear; Fig. 5 is atop View of outer end of showing how j ournalis hung in frame;

3 Fig. 6 is an end view of shaft, journal and pif 1 shaft Fig. 7 is aside View of bracket hanger at outer end of rollers, showing how thejournal move'sba'ck and 'fortli'as the inner end of rollersmoveup ordownwhen passing over uneven ground;

Fig. 8 is a side view of inner end of shaft with square box journalthereon, and

Fig. 9 is a top view thereof.

Similar letters refer to similar parts throughout the several views:

Referring to Figs. 1 and 2, the rollers are shown in two sections,inclosed by a frame B which is made from heavy steel bars. To this frameare fastened standards B. B near each end, and E in the middleprojecting below the frame in front and rear, and having holes boredthrough said pro ections. On these standards is placed the platform 0.supporting the seat D and also on which to place additional weight ifrequired. The

tongue is attached to the front at the standard E and braced to theframe B. Through the lower projections of the standard E a draw bolt orrod F. is placed, bolted to the tongue and extending to the rear offrame B, where it is secured by jam nuts which hold the frame rigid;outside of the jam nut is a knuckle to which a small roller can beattached as shown inFig. 4. This roller is to level down the small ridgeleft between the large rollers. On each corner of frame B. are fastenedbrackets Q on which is hung a shaft K, having a right and left handcoiled spring firmly fastened at each end to a lever J, and in themiddle to a ratchet wheel L. which is kept taut by the tension rod M.fastened to the ends of frame B. The outer ends of therollers A'arehungdirectly from frame B. but the inner ends are hung to an inner frameH.'which swings in frame B. on lugpins G., Figs. 2 and 3. i

It i by means of these pins that the rollers are allowed to raise andlower as they go over uneven ground. It will readily be seen j thatwhena roller strikes a knoll or high spot'it will rise and go over it,but when a hollow spot intervenes pressure will require 1 to be appliedto make it touch the low spots,

and give an even bearing. This may be done in various ways, by placingwei ht on the inner end, by automatic pressure or by a flat or coiledspring, of these plans I have adopted the coiled spring. To make thepressure effective I connect levers J and the ends of inner frame H. atR. with rods I show in Figs. 1 and 2.

To enable the rollers to work freely over uneven ground the inner end ofroller shaft N. Fig. 3, has a square boxing I) having a center hole 7'in which the pivots of the brackets a are inserted as shown in Figs. 8

and 9, said brackets being bolted to the inner frame H., part of boxingb is out way in Fig. 9 to show the pivots in the boxing. The outer endof shaft N. revolves in a journal 0, having pivots e, on each side,which hang in the slotted brackets P. attached to frame B. more fullyshown in Figs. 5 and 6. The dotted lines in Fig. 7, show how the journal0 moves back and forth as the inner end of roller moves up or down. Theboxing 6 and journal 0. are kept in place with a key a at each end ofthe shaft N.

To operate the rollers, the coiled springs are set to the requiredtension and held in place by a rod m catching 'oper the ratchet:
